Abstract
Random distributions of elements in a power schedule can be used to reduce interference in wireless communication networks with multiple transmitters. A random power schedule may be implemented by determining a first random power schedule for a first base station, wherein the first random power schedule is an orthogonal frequency division multiplexing (OFDM) schedule that associates a random distribution of a plurality of power levels with a corresponding plurality of time and frequency resources, assigning transmissions from the first base station to a plurality of mobile devices to the plurality of time and frequency resources, and transmitting data to the plurality of mobile devices at the respective plurality of power levels.
Claims20
A method for a wireless communications network, the method comprising:
- determining a first random power schedule for a first base station, wherein the first random power schedule is an orthogonal frequency division multiplexing (OFDM) schedule that associates a random distribution of a plurality of power levels with a corresponding plurality of time and frequency resources;
- assigning the plurality of time and frequency resources to a plurality of mobile devices;
- and
- transmitting data from the first base station to the plurality of mobile devices at the respective plurality of power levels.
A wireless communication system comprising:
- a first base station;
- one or more processor;
- and
- one or more non-transitory computer readable medium with computer-executable instructions stored thereon which, when executed by the one or more processor, perform the following operations:
- determining a first random power schedule for the first base station, wherein the first random power schedule is an orthogonal frequency division multiplexing (OFDM) schedule that associates a random distribution of a plurality of power levels with a corresponding plurality of time and frequency resources;
- assigning the plurality of time and frequency resources to a plurality of mobile devices;
- and
- transmitting data from the first base station to the plurality of mobile devices at the respective plurality of power levels.
